A few people over the years a few folks have posted who have VWB-2. My sister has a myloprolifc bone marrow condition and has "aquired" Von WIllebrand's which is her bodies compensation for too many platelets.
Mostly it's heretiday like hemopholia and like hemopholia is a missing factor in the clotting sequence. My sister had to have IV's of factor eight when they removed her spleen. The only way to know is to have testing done as Sandy says and if you're concerned it never hurts to discuss with the hemotologist.
I'd go back and re-read the article, increasing levels of VWB during pregnancy may mean that the body compensates and produces more factor eight as a protective mechanism for labor and delivery. There are just so many causes of heavy menstral issues (thyroid, fibroids, etc) that I won't take that as the only link to ITP without some additional symptoms.
